MACHINE FOR CASTING METAL.

sPEcIrIcATIoN'ferming part of Letters Patent No. 746,245, dated December8,1903.

j Application filed March 16, 1903. Serial No. 147.985. (No model.)

of Fig. 1,and Fig. is a plan view of the mail chine.

The operation ofcasting-copper pigs as heretofore conducted has beenvery wasteful, not- Vonly because the apparatus which has beenv employedcauses the spilling of a considerable portion of the metal in pouring itinto the molds, but also because the pigs are cast with fins, which,absorbing oxygen from the air,become very brittle and break olf inhandling and shipping, thus occasioning a very considerable loss. v

The object of my-invention is top provide means whereby the presentlosses resulting from the shipment of copper, whether the same be inpigs, slabs, or bars, may be elimi nated. To accomplish this result, Iusel a water-jacketed mold which is closed at thelower end and is shapedto give the pig the desired conformation. The ingot castv therein hasall its iins concentrated at the upper open end of the mold, and thetins when so concentrat-ed may be readily removed by suitable cuttingortrimming machines, so that in pouring and shipping nop-art of the copperwill be broken loose and lost.

In the accompanying drawings, 2 represents the frame of the machine, and3 is the mold, which is of greater height than width and is formed withhollow walls 4 for the passage of a stream of Water and with trunnionsv5 5 at about the middle of its height through which inlet and outletpipes 7 and Sextend for the introduction of water to cool the mold. Thewater enters a chamber 4 at one side of the mold, from the top of whichit' overflows through a passage 4a into the'main water-passage aroundthe mold-cavity. Thence afftpr lling the main cavity it iiows through apassage 4b at the top into a side chamber 4c,

the machine-frame and adapted to constitu te from which it iiows throughthe outlet-pipe 8. Y'

As the mold is lling the air rises to the top of the chambers and isdisplaced through the passages 4a and 4b and is caused to go out throughthe pipe 8. To rotate the mold on its trunnions, I prefer to employ apinion 9, fixed to one of the trunnions and operated bya rack 10, xed toand movable with a cylindex' 11, which is reciprocated on a plunger 12,the latter being hollow and serving for the introduction and dischargeofthe water or compressed air by which the cylinder is operated. The lowerend of the mold is shaped'with an inwardly-projecting portion, as shownin Fig. 4, so as to form an ingot with a concave end, which is of veryconvenient form for handling, and I preferably set in 4the mold adetachable piece 13, which forms in the oase of the concavity a rosetteor tablet portion 14, Fig. 2, on which thev name of the person for whomthe `ingot is made may be cast or the weight of the ingot may be stamped.

As the upper end 0f the mold is open, the top 'of the ingot isirregularin form, and all the fins being concentrated'at that end may readily betrimmed off by machinery after the Y ingot has been discharged from themold.

15 15 are wheelsjournaled in uprights of rests for the t-runnion of theladle, and 15' is the mold.

The parts being in the position shown in Fig. 1, molten metalv ischarged into the ladle 16 from a furnace or converter in proximity towhich the casting-machine is set,'and the ladle is tilted on the wheels15, so as to teem the molten copper into the mold. The mold has acapacity a little in excess of the capacity of the ladle, so that theladle may be emptied into the mold. There is-therefore no surplus ofmetal and no loss in pouring. pig has been cast, the ladle is rightedandthe mold is rotated on its axis into an inverted y position,whereupon the pig drops` from the open end of the mold, the mold-cavitybeing of flaring shape, so as to cause its discharge'. The mold can thenbeuighted land another pig cast therein. The operation is thus veryrapid and can be carried on with the labor. of only one man. l

Fins which are trimmed from the pigs can `a spout to conduct the metalto the cavity of y When the' Y y roo.,

be returned to the refining-furnace for retreatment or, if desired, tothe mold and become incorporated in the next pig that is cast.

Within the scope of my invention the apparatus may be modified inVarious Ways, since What I claim, and desire t0 secure by LettersPatent, is-

l. A machine for casting copper pige, having a wetter-cooled mold openat the top and provided with a closed inwardly-projecting bottom portionadapted to form a hand-hole on the bottom of the pig; substantially asdescribed.

2. A machine for casting Copper pigs, having a water-cooled mold open atthe top and provided With a. closed inwardly-projecting bottom portionadapted to form a hand-hole 0n the bottom of the pig, and with a,detachable piece on said inwardly-projecting p0rtion adapted to cast e,distinguishing-mark at the end of the concavity; substantially asdescribed.

In testimony whereof I have hereunto set my hand.
